AP-FASTENER.

"Application filed April 17, 1920. Serial No. 374,704.

To all whom it may concern:

Be it known that I, THoMAs F MORRIS, a citizen of the United States of America, residing at, Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Snap-Fasteners, of which the following is a specification.

This invention relates to an improvement in snap fasteners, designed more particularly for use on gloves and the like, and wherein means are provided to prevent separation ofthe fastener member from the glove material under strain or stretching of said material in use.

Snap fasteners of this type are applied in part through an opening formed in the material, and complementary parts of the fastener are forced, under clamping cooperation of the fastener parts into contact with opposite surfaces of the fabric. Un-

der the strain and stretching of the fabric.

with the fastener in use. or in drawing on the glove, there is a tendency to stretch or enlarge the opening through which the fastener is originally passed, and this fre quently results in such an enlargement of the opening as to actually separate the fastener from the material. I

The present invention is. directed par -ticularly to overcoming this tendency of opening enlargement under strain or stretching of the fabric, by providing an auxiliary securing means, integral withthe part ofthe fastener, and adapted in the clamping action necessary to iii: the coop.-

erating parts of the fastening elements to the fabric, to be 'so moved as to engage and hold the fabric'about and'beyond said opening, the securing means being so arranged as to prevent any possibility of opening enlargement under any ordinary strains or stretching to which the fabric may be subjected. I

In the drawings Figure'l is a vertical sectional view showing one type of the male member of a snap fastener, with the parts in'cooperating rel 4- tion prior tothe setting pressure.

Fig. 2 is a similar view following the application of the clamping pressure, and showing the malemember as finally secured in the fabric; V

Fig. 3 is a vertical sectionalview of a complete fastener, with the improved se ouring'means in both the maleand female in Fig. 1.,

members, the male being shown of a type somewhat different from that shown. in Figs. 1 and 2'.

Fig. 4 is a perspective view of the fastening member used in theform illustrated Fig. '5' is a similar view. of the fastening member used in the form shown in F ig. 3 i The improved snap fastener, includes as usual the male member 1 and-female member 2, adapted to be secured to differentfabric sections, to permit the connection or disconnection of such sections in the usual manner. The present invention is directed particularly to providing an auxiliary fastening means whereby the complementary parts of either the male or female member, act, when applied, to hold the fabric against the possibility of stretching: to enlargethe and a disk-like element 8 to overlie: the up- I per surface 'of the fabricin opposition to the disk 3. e F Q The characteristic detail of the present invention residesin providing one of the disks 3 or, 8 as here shown the disk-3,iwith a series of spurs 9,- preferably stamped from the disk and extending upwardly therefrom and inclined from the vertical toward the stud 4. These spurs 9 are preferably not of a length to extend materially through and beyond the fabric in the application of the parts, as will be particularly clear'from Fig. 1 of the drawings. In fixing the element 7 to the element 3, the disk 3, or'that disk having the spurs is arranged with the spurs in engagement with the surface of'the fabric, the cooperating parts are positioned, and a clamping pressure is applied to the disks 3 and 8, the upper end of the stud 4 being simultaneously enlarged withinYthe vide the conventional snap head. Under this pressure the disks. 3 and 8 will" be until finally said studs forced toward each other, compressing the fabric between said disks, and as the pressure continues, the free ends of sa1d studs 9 are forced into the fabric and at the same time bent downwardly, thus bending the a strain of the fabric has gradually enlarged more or .lesscompress the fabric betweenthe hole 5, so that eventually the snap fastener part is substantially free from the fabric. ith the oresent invention however it is to be noted t at this hole enlargement is impossible, as any stretching or strain on the fabric tending to such hole enlargement, is immediately resisted by one or more of the studs 9, with the effect of maintaining the fabric between the disks 8 and 8 in sub stantially its original condition.

In the result gained by this construction it is to be noted that the fabric between the disks 3 and 8 is, through the compression thereof by the clamping pressure of the disks, substantially hardened or rendered more compact, and hence the effectiveness of the holding action of the studs 9 is materially increased. Furthermore it is to be noted that the suds 9 do not pass to any appreciable extent through and beyond the fabric and that when bent down by the clamping pressure they form no additional opening in the fabric beyond that formed in their original application. This causes the studs to them and the stud't, which of course tends to increase the holding effect of the studs.

' In Fig.3 the invention is shown as applied to a slightly different, though well known type of'head member of a snap fastener. In

this figure the head proper 10 is provided with a disk 1-1 to overlie the upper portion of the fabric and has an integral stud 12 .which passes through the opening 13 in the fabric. The member engaging the lower surface of the fabric is here shown as a washer-like element 14, adapted to encircle the projecting end of the stud '12. This ele- 'ment 14,- which' corresponds to the disk 3 in the. form first described is provided with studs '15, which in applying the parts operate exactly as described in connection with the studs 9.

and at the same time the projecting end'of the stud12 is upset beneath the washer 14 to hold theparts in clamped relation.

In- Fig. 3, the invention is Shown as applied to the socket member of the head fastener, to whichof course it is as readily applicable as to the head member of such fastener. The socket member here shown, is of conventional form, andneeds no description in detail other than indicating the studs 16,

It is of course apparent that the spurs 9 i may, with equal facility and eflect, be applied to either clamping disk, "and while the particular disk employed for such spurs, is more convenient, any other application of such is contemplated.

Claims: Y 1. A snap fastener member including a part to pass through an opening in; the material and also including disks adapted to be clamped on the material beyond said opening, and spurs projecting from one of said disks to be deflectedtoward the opening in the clamping of the disks. 1 2. A snap fastener member comprising disks betweenwhich the material is to be clamped by pressure on s'aiddisks, a stud carried by one of saiddisks to pass through an opening in the material, and spurs carried by one of said disksand normally inclined from the vertical toward said opening, said spurs'being further deflected inthe direction of their normal inclination as the clamping pressure is applied to the disks.-

3. A snap fastener member comprising disks between which the materialis held under a clamping pressure, and means carried disks between which the material is tobe I held by clamping'pressure, and spurs car- 'ried by one of saiddisks to. extend substantially through the material between the disks and. at an inclination to the plane and In this form the clamping pressure is applied to the disks 11 and 14,

toward the center of the'disksa 5; A snap fastener'member to be held in a hole in the material and'including disks between which the material adjacent and surrounding said hole is clamped, and spurs carried by one of the disksto enter the material between the disks and extend substantially through the same at an inclination toward the center of the disk on which they are 'carried. I

A- snap fastener member comprising snap fastener member including disks between which theqinaterial is 'cofn- V pressed under a clamping action of the disks, and means carried by one of "said disks and inclined towardthe c'enter'thereof, said means being adapted to ext'end' substantially through the compressed portion of said material and to be deflected by the clamping action to dispose the means at an inclination to the plane of the disks and in a direction to resist displacement of the ma terial between the disks.

7. A snap fastener comprising disks between which the material is adapted to be clamped, said disks encircling an opening in said material, and spurs carried by one of the disks and adapted under the clamping action of the disks to be inclined toward the opening to thereby hold the material about said opening against displacement relative to said disks.
